     2.6. Trust Enforcement Events; Waiver.

     (a) The Holders of a Majority in Liquidation Amount of the Capital
Securities may, by vote or written consent, on behalf of the Holders of all of
the Capital Securities, waive any past Trust Enforcement Event in respect of the
Capital Securities and its consequences, provided that, if the underlying
Indenture Event of Default:

          (i) is not waivable under the Indenture, the Trust Enforcement Event
     under the Trust Agreement shall also not be waivable; or

          (ii) requires the consent or vote of the Holders of greater than a
     majority in principal amount of the Debentures (a "Super Majority") to be
     waived under the Indenture, the related Trust Enforcement Event under the
     Trust Agreement may only be waived by the vote or written consent of the
     Holders of at least the proportion in liquidation amount of the Capital
     Securities that the relevant Super Majority represents of the aggregate
     principal amount of the Debentures outstanding.

          The foregoing provisions of this Section 2.6(a) shall be in lieu of
     Section 316(a)(1)(B) of the Trust Indenture Act and such Section
     316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from
     this Trust Agreement and the Securities, as permitted by the Trust
     Indenture Act. Upon such waiver, any such default shall cease to exist, and
     any Trust Enforcement Event with respect to the Capital Securities arising
     therefrom shall be deemed to have been cured, for every purpose of this
     Trust Agreement and the Capital Securities, but no such waiver shall extend
     to any subsequent or other Trust Enforcement Event with respect to the
     Capital Securities or impair any right consequent thereon. Any waiver by
     the Holders of the Capital Securities of a Trust Enforcement Event with
     respect to the Capital Securities shall also be deemed to constitute a
     waiver by the Holders of the Common Securities of any such Trust
     Enforcement Event with respect to the Common Securities for all purposes of
     this Trust Agreement without any further act, vote, or consent of the
     Holders of the Common Securities.

     (b) The Holders of a Majority in Liquidation Amount of the Common
Securities may, by vote or written consent, on behalf of the Holders of all of
the Common Securities, waive any past Trust Enforcement Event in respect of the
Common Securities and its consequences, provided that, if the underlying
Indenture Event of Default:

          (i) is not waivable under the Indenture, except where the Holders of
     the Common Securities are deemed to have waived such Trust Enforcement
     Event under the Trust Agreement as provided below in this Section 2.6(b),
     the Trust Enforcement Event under the Trust Agreement shall also not be
     waivable; or

          (ii) requires the consent or vote of a Super Majority to be waived
     under the Indenture, except where the Holders of the Common Securities are
     deemed to have waived such Trust Enforcement Event under the Trust
     Agreement as provided below in this Section 2.6(b), the Trust Enforcement
     Event under the Trust Agreement may only be waived by the vote or written
     consent of the Holders of at least the proportion in liquidation amount of
     the

                                       10

<PAGE>

     Common Securities that the relevant Super Majority represents of the
     aggregate principal amount of the Debentures outstanding; provided further,
     each Holder of Common Securities will be deemed to have waived any Trust
     Enforcement Event and all Trust Enforcement Events with respect to the
     Common Securities and the consequences thereof until all Trust Enforcement
     Events with respect to the Capital Securities have been cured, waived or
     otherwise eliminated, and until such Trust Enforcement Events with respect
     to the Capital Securities have been so cured, waived or otherwise
     eliminated, the Property Trustee will be deemed to be acting solely on
     behalf of the Holders of the Capital Securities and only the Holders of the
     Capital Securities will have the right to direct the Property Trustee in
     accordance with the terms of the Securities. The foregoing provisions of
     this Section 2.6(b) shall be in lieu of Sections 316(a)(1)(A) and
     316(a)(1)(B) of the Trust Indenture Act and such Sections 316(a)(1)(A) and
     316(a)(1)(B) of the Trust Indenture Act are hereby expressly excluded from
     this Trust Agreement and the Securities, as permitted by the Trust
     Indenture Act. Subject to the foregoing provisions of this Section 2.6(b),
     upon such cure, waiver or other elimination, any such default shall cease
     to exist and any Trust Enforcement Event with respect to the Common
     Securities arising therefrom shall be deemed to have been cured for every
     purpose of this Trust Agreement, but no such waiver shall extend to any
     subsequent or other Trust Enforcement Event with respect to the Common
     Securities or impair any right consequent thereon.

     (c) A waiver of an Indenture Event of Default by the Property Trustee at
the direction of the Holders of the Capital Securities constitutes a waiver of
the corresponding Trust Enforcement Event with respect to the Capital Securities
under this Trust Agreement. The foregoing provisions of this Section 2.6(c)
shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such
Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded
from this Trust Agreement and the Securities, as permitted by the Trust
Indenture Act.

     2.7. Trust Enforcement Event; Notice.

     (a) The Property Trustee shall, within 90 days after the occurrence of a
Trust Enforcement Event actually known to a Responsible Officer of the Property
Trustee, transmit by mail, first class postage prepaid, to the Holders of the
Securities, notices of all such defaults with respect to the Securities, unless
such defaults have been cured before the giving of such notice (the term
"defaults" for the purposes of this Section 2.7(a) being hereby defined to be an
Indenture Event of Default, not including any periods of grace provided for
therein and irrespective of the giving of any notice provided therein); provided
that, except for a default in the payment of principal of (or premium, if any)
or interest on any of the Debentures, the Property Trustee shall be protected
fully in withholding such notice if and so long as a Responsible Officer of the
Property Trustee in good faith determines that the withholding of such notice is
in the interests of the Holders of the Securities.

     (b) The Property Trustee shall not be deemed to have knowledge of any
default except:

          (i) a default under Sections 5.1(a) and 5.1(b) of the Indenture; or

                                       11

<PAGE>

          (ii) any default as to which the Property Trustee shall have received
     written notice or of which a Responsible Officer of the Property Trustee
     charged with the administration of this Trust Agreement shall have actual
     knowledge.

                                    ARTICLE 3

<PAGE>

          (i) causing the Trust not to be deemed to be an Investment Company
     required to be registered under the Investment Company Act;

          (ii) causing the Trust to be classified as a grantor trust for United
     States federal income tax purposes; and

          (iii) cooperating with the Debenture Issuer to ensure that the

     United States federal income tax purposes.

     (p) to take all action necessary to cause all applicable tax returns and
tax information reports that are required to be filed with respect to the Trust
to be duly prepared and filed by the Administrative Trustees, on behalf of the

or authorized by this Trust Agreement. In particular, the Trust shall not and
none of the Trustees (including the Property Trustee) shall cause the Trust to:

          (i) invest any proceeds received by the Trust from holding the
     Debentures, but shall distribute all such proceeds to Holders of Securities
     pursuant to the terms of this Trust Agreement and of the Securities;

          (ii) acquire any assets other than as expressly provided herein;

          (iii) possess Trust property for other than a Trust purpose;

                                       15

<PAGE>

          (iv) make any loans (other than those represented by the Debentures)
     or incur any indebtedness;

     the Debentures where such consent shall be required unless the Trust shall
     have received an opinion of counsel to the effect that such modification
     will not cause more than an insubstantial risk that the Trust will be
     deemed an Investment Company required to be registered under the Investment
     Company Act, or the Trust will be classified as other than a grantor trust
     for United States federal income tax purposes;

          (ix) take any action inconsistent with the status of the Trust as a
     grantor trust for United States federal income tax purposes; or

of the Securities. The right, title and interest of the Property Trustee to the
Debentures shall vest automatically in each Person who may hereafter be
appointed as Property Trustee in accordance with Section 6.6. Such vesting and
cessation of title shall be effective whether or not conveyancing documents with
regard to the Debentures have been executed and delivered.

     (b) The Property Trustee shall not transfer its right, title and interest
in the Debentures to the Administrative Trustees or to the Delaware Trustee (if
the Property Trustee does not also act as Delaware Trustee).

                                       16

<PAGE>

     (c) The Property Trustee shall:

          (i) establish and maintain a segregated non-interest bearing trust
     account (the "Property Account") in the name of and under the exclusive
     control of the Property Trustee on behalf of the Holders of the Securities
     and, upon the receipt of payments of funds made in respect of the
     Debentures held by the Property Trustee, deposit such funds into the
     Property Account and make payments to the Holders of the Capital Securities
     and Holders of the Common Securities from the Property Account in
     accordance with Section 7.2. Funds in the Property Account shall be held
     uninvested until disbursed in accordance with this Trust Agreement. The
     Property Account shall be an account that is maintained with a banking
     institution the rating on whose long-term unsecured indebtedness is at
     least equal to the rating assigned to the Capital Securities by a
     "nationally recognized statistical rating organization", within the meaning
     of Rule 436(g)(2) under the Securities Act;

          (ii) engage in such ministerial activities as shall be necessary or
     appropriate to effect the redemption of the Capital Securities and the
     Common Securities to the extent the Debentures are redeemed or mature; and

          (iii) upon written notice of distribution issued by the Administrative
     Trustees in accordance with the terms of the Securities, engage in such
     ministerial activities as so directed and as shall be necessary or
     appropriate to effect the distribution of the Debentures to Holders of
     Securities upon the occurrence of a Special Event.

     (d) The Property Trustee shall take all actions and perform such duties as
may be specifically required of the Property Trustee pursuant to the terms of
this Trust Agreement and the Securities.

     (e) The Property Trustee shall take any Legal Action which arises out of or
in connection with a Trust Enforcement Event of which a Responsible Officer of
the Property Trustee has actual knowledge or the Property Trustee's duties and
obligations under this Trust Agreement or the Trust Indenture Act; provided,
however, that if a Trust Enforcement Event has occurred and is continuing and
such event is attributable to the failure of the Debenture Issuer to pay
interest, principal or other required payments on the Debentures on the date
such interest, principal or other required payments are otherwise payable (or in
the case of redemption, on the redemption date), then a Holder of Capital
Securities may directly institute a proceeding against the Debenture Issuer for
enforcement of payment to such Holder of the principal of or interest on
Debentures having a principal amount equal to the aggregate liquidation amount
of the Capital Securities of such Holder (a "Direct Action") on or after the
respective due date specified in the Debentures. Notwithstanding anything to the
contrary in this Trust Agreement or the Indenture, the Debenture Issuer shall
have the right to set-off any payment it is otherwise required to make under the
Indenture in respect of any Capital Security to the extent the Debenture Issuer

     (f) The Property Trustee shall continue to serve as a Trustee until either:

          (i) the Trust has been completely liquidated and the proceeds of the
     liquidation distributed to the Holders of Securities pursuant to the terms
     of the Securities; or

          (ii) a Successor Property Trustee has been appointed and has accepted
     that appointment in accordance with Section 6.6.

     (g) The Property Trustee shall have the legal power to exercise all of the
rights, powers and privileges of a holder of Debentures under the Indenture and,
if a Trust Enforcement Event actually known to a Responsible Officer of the
Property Trustee occurs and is continuing, the Property Trustee shall, for the
benefit of Holders of the Securities, enforce its rights as holder of the
Debentures subject to the rights of the Holders pursuant to the terms of such
Securities.

     (h) The Property Trustee may authorize one or more Persons (each, a "Paying
Agent") to pay Distributions, redemption payments or liquidation payments on
behalf of the Trust with respect to all Securities and any such Paying Agent

Event and after the curing of all Trust Enforcement Events that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Trust Agreement and no implied covenants shall be read into this
Trust Agreement against the Property Trustee. In case a Trust Enforcement Event
has occurred (that has not been cured or waived pursuant to Section 2.6) of
which a Responsible Officer of the Property Trustee has actual knowledge, the
Property Trustee shall exercise such of the rights and powers vested in it by
this Trust Agreement, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

     (b) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that:


                                       18
<PAGE>

          (i) prior to the occurrence of a Trust Enforcement Event and after the
     curing or waiving of all such Trust Enforcement Events that may have
     occurred:

               (A) the duties and obligations of the Property Trustee shall be
          determined solely by the express provisions of this Trust Agreement
          and the Property Trustee shall not be liable except for the
          performance of such duties and obligations as are specifically set
          forth in this Trust Agreement, and no implied covenants or obligations
          shall be read into this Trust Agreement against the Property Trustee;
          and

               (B) in the absence of bad faith on the part of the Property
          Trustee, the Property Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Property
          Trustee and conforming to the requirements of this Trust Agreement;
          but in the case of any such certificates or opinions that by any
          provision hereof are specifically required to be furnished to the
          Property Trustee, the Property Trustee shall be under a duty to
          examine the same to determine whether or not they conform to the
          requirements of this Trust Agreement;

          (ii) the Property Trustee shall not be liable for any error of
     judgment made in good faith by a Responsible Officer of the Property
     Trustee, unless it shall be proved that the Property Trustee was negligent
     in ascertaining the pertinent facts;

          (iii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it without negligence, in good faith
     in accordance with the direction of the Holders of not less than a Majority
     in Liquidation Amount of the Securities relating to the time, method and
     place of conducting any proceeding for any remedy available to the Property
     Trustee, or exercising any trust or power conferred upon the Property
     Trustee under this Trust Agreement;

          (iv) no provision of this Trust Agreement shall require the Property
     Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers, if it shall have reasonable
     grounds for believing that the repayment of such funds or liability is not
     reasonably assured to it under the terms of this Trust Agreement or
     indemnity reasonably satisfactory to the Property Trustee against such risk
     or liability is not reasonably assured to it;

          (v) the Property Trustee's sole duty with respect to the custody,
     safe-keeping and physical preservation of the Debentures and the Property
     Account shall be to deal with such property in a similar manner as the
     Property Trustee deals with similar property for its own account, subject
     to the protections and limitations on liability afforded to the Property
     Trustee under this Trust Agreement and the Trust Indenture Act;

          (vi) the Property Trustee shall have no duty or liability for or with
     respect to the value, genuineness, existence or sufficiency of the
     Debentures or the payment of any taxes or assessments levied thereon or in
     connection therewith;

          (vii) the Property Trustee shall not be liable for any interest on any



                                       19

     money received by it except as it may otherwise agree with the Sponsor.
     Money held by the Property Trustee need not be segregated from other funds
     held by it except in relation to the Property Account maintained by the
     Property Trustee pursuant to Section 3.8(c)(i) and except to the extent
     otherwise required by law; and

          (viii) the Property Trustee shall not be responsible for monitoring
     the compliance by the Administrative Trustees or the Sponsor with their
     respective duties under this Trust Agreement, nor shall the Property
     Trustee be liable for any default or misconduct of the Administrative
     Trustees or the Sponsor.

     3.10. Certain Rights of Property Trustee.

     (a) Subject to the provisions of Section 3.9:

     established before taking, suffering or omitting any action hereunder, the
     Property Trustee (unless other evidence is herein specifically prescribed)
     may, in the absence of bad faith on its part, request and conclusively rely
     upon an Officers' Certificate which, upon receipt of such request, shall be
     promptly delivered by the Sponsor or the Administrative Trustees;

          (iv) the Property Trustee shall have no duty to see to any recording,
     filing or registration of any instrument (including any financing or
     continuation statement or any filing under tax or securities laws) or any
     rerecording, refiling or registration thereof;

          (v) the Property Trustee may consult with counsel of its choice or
     other experts and the advice or opinion of such counsel and experts with
     respect to legal matters or advice within the scope of such experts' area

     respect of any action taken, suffered or omitted by it hereunder in good
     faith and in accordance with such advice or opinion, such counsel may be
     counsel to the Sponsor or any of its Affiliates, and may include any of its
     employees. The Property Trustee shall have the right at any time to seek
     instructions concerning the administration of this Trust Agreement from any
     court of competent jurisdiction;

          (vi) the Property Trustee shall be under no obligation to exercise any
     of the rights or powers vested in it by this Trust Agreement at the request
     or direction of any Holder, unless such Holder shall have provided to the
     Property Trustee security and indemnity,



                                       20
<PAGE>

     reasonably satisfactory to the Property Trustee, against the costs,
     expenses (including reasonable attorneys' fees and expenses and the
     expenses of the Property Trustee's agents, nominees or custodians) and
     liabilities that might be incurred by it in complying with such request or
     direction, including such reasonable advances as may be requested by the
     Property Trustee; provided that, nothing contained in this Section 3.10(a)
     shall be taken to relieve the Property Trustee, upon the occurrence of a
     Trust Enforcement Event, of its obligation to exercise the rights and
     powers vested in it by this Trust Agreement;

          (vii) the Property Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,

     defined in Section 7701(a)(30) of the Code;

          (ix) any authorized or required action taken by the Property Trustee
     or its agents hereunder shall bind the Trust and the Holders of the
     Securities, and the signature of the Property Trustee or its agents alone
     shall be sufficient and effective to perform any such action and no third
     party shall be required to inquire as to the authority of the Property
     Trustee to so act or as to its compliance with any of the terms and
     provisions of this Trust Agreement, both of which shall be conclusively
     evidenced by the Property Trustee's or its agent's taking such action;

          (x) whenever in the administration of this Trust Agreement the
     Property Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Property Trustee (i) may request instructions from the
     Holders of the Securities which instructions may only be given by the
     Holders of the same proportion inliquidation amount of the Securities as
     would be entitled to direct the Property Trustee under the terms of the
     Securities in respect of such remedy, right or action, (ii) may refrain
     from enforcing such remedy or right or taking such other action until such
     instructions are received, and (iii) shall be protected in conclusively

     upon it by this Trust Agreement;

          (xiii) without prejudice to any other rights available to the Property
     Trustee under applicable law, when the Property Trustee incurs expenses or
     renders services in connection with a bankruptcy, such expenses (including
     the fees and expenses of its counsel) and the compensation for such
     services are intended to constitute expenses of administration under any
     bankruptcy law or law relating to creditors rights generally; and

          (xiv) the Property Trustee shall not be charged with knowledge of a
     Trust Enforcement Event unless a Responsible Officer of the Property
     Trustee obtains actual knowledge of such event or the Property Trustee
     receives written notice of such event from Holders holding more than a
     Majority in Liquidation Amount of the Capital Securities;


     (b) No provision of this Trust Agreement shall be deemed to impose any duty
or obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

     3.11. Delaware Trustee. Notwithstanding any other provision of this Trust
Agreement other than Section 6.2, the Delaware Trustee shall not be entitled to
exercise any powers, nor shall the Delaware Trustee have any of the duties and
responsibilities of the Administrative Trustees or the Property Trustee
described in this Trust Agreement. Except as set forth in Section 6.2, the
Delaware Trustee shall be a Trustee for the sole and limited purpose of
fulfilling the requirements of Section 3807(a) of the Business Trust Act. In the

be entitled to all of the same rights as the Property Trustee listed in Section
3.9(b) and Section 3.10.

     3.12. Execution of Documents. Except as otherwise required by the Business

representations as to the validity or sufficiency of this Trust Agreement, the
Securities, the Debentures or the Indenture.

     3.15. Mergers.

     (a) The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, except as described in Section
3.15(b) and (c) or Section 8.2.

     (b) The Trust may, at the request of the Sponsor and with the consent of
the Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees and without the consent of the Holders of the
Securities, the Delaware Trustee or the Property Trustee, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties substantially as an entirety to a trust organized as such under
the laws of any State; provided, that:

          (i) if the Trust is not the successor, such successor entity (the
     "Successor Entity") either:

               (A) expressly assumes all of the obligations of the Trust with
          respect to the Securities; or

               (B) substitutes for the Capital Securities other securities
          having substantially the same terms as the Capital Securities (the
          "Successor Securities") so long as the Successor Securities rank the
          same as the Capital Securities rank in priority with respect to
          Distributions and payments upon liquidation, redemption and otherwise;

          (ii) the Debenture Issuer expressly appoints a trustee of such
     Successor Entity that possesses the same powers and duties as the Property
     Trustee as the holder of the Debentures;

          (iii) the Capital Securities or any Successor Securities are listed,
     or any Successor Securities will be listed upon notification of issuance,
     on any national securities exchange or with any other or organization on
     which the Capital Securities are then listed or quoted;

          (iv) such merger, consolidation, amalgamation, replacement,
     conveyance, transfer or lease does not cause the Capital Securities
     (including any Successor Securities) to be downgraded by any nationally
     recognized statistical rating organization;

          (v) such merger, consolidation, amalgamation, replacement, conveyance,
     transfer or lease does not adversely affect the rights, preferences and
     privileges of the Holders of the Capital Securities (including any
     Successor Securities) in any material respect;

          (vi) such Successor Entity has a purpose substantially identical to
     that of the Trust;

          (vii) prior to such merger, consolidation, amalgamation, replacement,
     conveyance, transfer or lease the Sponsor has received an opinion of
     counsel to the Trust



                                       23
<PAGE>

     experienced in such matters to the effect that:

               (A) such merger, consolidation, amalgamation, replacement,
          conveyance, transfer or lease does not adversely affect the rights,
          preferences and privileges of the Holders of the Capital Securities
          (including any Successor Securities) in any material respect;

               (B) following such merger, consolidation, amalgamation,
          replacement, conveyance, transfer or lease neither the Trust nor the
          Successor Entity will be required to register as an Investment
          Company; and

               (C) following such merger, consolidation, amalgamation or
          replacement, the Trust (or the Successor Entity) will continue to be
          classified as a grantor trust for United States federal income tax
          purposes;

          (viii) the Sponsor or any permitted successor or assignee owns all of
     the common securities and guarantees the obligations of such Successor
     Entity under the Successor Securities at least to the extent provided by
     the Securities Guarantee and such Successor Entity expressly assumes all of
     the obligations of the Trust with respect to the Trustees.

     (c) Notwithstanding Section 3.15(b), the Trust shall not, except with the
consent of Holders of 100% in aggregate liquidation amount of the Securities,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to, any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it, if such consolidation, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Trust or Successor
Entity to be classified as other than a grantor trust for United States federal
income tax purposes and each Holder of the Securities not to be treated as
owning an undivided interest in the Debentures.

     3.16. Property Trustee May File Proofs of Claim. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other similar judicial proceeding
relative to the Trust or any other obligor upon the Securities or the property
of the Trust or of such other obligor or their creditors, the Property Trustee
(irrespective of whether any Distributions on the Securities shall then be due
and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Property Trustee shall have made any demand on the Trust for the
payment of any past due Distributions) shall be entitled and empowered, to the
fullest extent permitted by law, by intervention in such proceeding or
otherwise:

     (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Securities (or, if the Securities are
original issue discount Securities, such portion of the liquidation amount as
may be specified in the terms of such Securities) and to file such other papers
or documents as may be necessary or advisable in order to have the claims of the
Property Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its and counsel) and of the
Holders allowed in such judicial proceeding, and



                                       24
<PAGE>

     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Property Trustee and, in the event the Property Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Property Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its agents and counsel, and
any other amounts due the Property Trustee.

     Nothing herein contained shall be deemed to authorize the Property Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement adjustment or compensation affecting the
Securities or the rights of any Holder thereof or to authorize the Property
Trustee to vote in respect of the claim of any Holder in any such proceeding.

liability or expense incurred without negligence or bad faith on the part of the
Property Trustee or the Delaware Trustee, as the case may be, arising out of or
in connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses of defending either of them against
any claim or liability in connection with the exercise or performance of any of
their respective powers or duties hereunder; the provisions of this Section 4.2

<PAGE>

Delaware Trustee or the Property Trustee or the termination of this Trust
Agreement.

up, liquidate or be terminated, except as permitted by this Trust Agreement,
(iii) to use its commercially reasonable efforts to ensure that the Trust will
not be an investment company for purposes of the Investment Company Act, and

purposes.

     (c) notwithstanding clause (a), unless a Trust Enforcement Event shall have
occurred and be continuing, at any time or times, for the purpose of meeting the
legal requirements of the Trust Indenture Act or of any jurisdiction in which
any part of the Trust's property may at the time be located, the Holders of a
Majority in Liquidation Amount of the Common Securities, and the Administrative

act under Section 6.3(a), the Property Trustee shall immediately resign in the
manner and with the effect set forth in Section 6.6(c).

     (c) If the Property Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Property
Trustee and the Holder of the Common Securities (as if it were the obligor
referred to in Section 310(b) of the Trust Indenture Act) shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act.

     (d) The Guarantee shall be deemed to be specifically described in this

                                       28
<PAGE>

          (ii) after the issuance of any Securities (but prior to the occurrence
     of an Indenture Event of Default), by vote of the Holders of a Majority in
     Liquidation Amount of the Common Securities voting as a class at a meeting
     of the Holders of the Common Securities; and

          (iii) after the issuance of the Capital Securities and the occurrence
     of an Indenture Event of Default, and only with respect to each of the
     Property Trustee and Delaware Trustee, by vote of the Holders of a Majority
     in Liquidation Amount of the Capital Securities.

     (b) The Trustee that acts as Property Trustee shall not be removed in
accordance with Section 6.6(a) until a successor Trustee possessing the
qualifications to act as Property Trustee under Section 6.3(a) (a "Successor
Property Trustee") has been appointed and has accepted such appointment by
written instrument executed by such Successor Property Trustee and delivered to
the Administrative Trustees and the Sponsor. The Trustee that acts as Delaware
Trustee shall not be removed in accordance with Section 6.6(a) until a successor
Trustee possessing the qualifications to act as Delaware Trustee under Sections
6.2 and 6.4 (a "Successor Delaware Trustee") has been appointed and has accepted
such appointment by written instrument executed by such Successor Delaware
Trustee and delivered to the Administrative Trustees and the Sponsor.

     (c) A Trustee appointed to office shall hold office until his or its
successor shall have been appointed, until his death or its dissolution or until
his or its removal or resignation. Any Trustee may resign from office (without
need for prior or subsequent accounting) by an instrument in writing signed by
the Trustee and delivered to the Sponsor and the Trust, which resignation shall
take effect upon such delivery or upon such later date as is specified therein;
provided, however, that:

          (i) no such resignation of the Trustee that acts as the Property
     Trustee shall be effective:

                    (A) until a Successor Property Trustee has been appointed
               and has accepted such appointment by instrument executed by such
               Successor Property Trustee and delivered to the Trust, the
               Sponsor and the resigning Property Trustee; or

                    (B) until the assets of the Trust have been completely
               liquidated and the proceeds thereof distributed to the holders of
               the Securities; and

          (ii) no such resignation of the Trustee that acts as the Delaware
     Trustee shall be effective until a Successor Delaware Trustee has been
     appointed and has accepted such appointment by instrument executed by such
     Successor Delaware Trustee and delivered to the Trust, the Sponsor and the
     resigning Delaware Trustee.

     (d) The Holders of the Common Securities shall use their best efforts to
promptly appoint a Successor Delaware Trustee or Successor Property Trustee, as
the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in



                                       29
<PAGE>

accordance with this Section 6.6.

     (e) If no Successor Property Trustee or Successor Delaware Trustee, as the
case may be, shall have been appointed and accepted appointment as provided in
this Section 6.6 within 60 days after delivery to the Sponsor and the Trust of
an instrument of resignation or removal, the resigning or removed Property
Trustee or Delaware Trustee, as applicable, may petition any court of competent
jurisdiction in the U.S. for appointment of a Successor Property Trustee or
Successor Delaware Trustee, as applicable. Such court may thereupon, after
prescribing such notice, if any, as it may deem proper, appoint a Successor
Property Trustee or Successor Delaware Trustee, as the case may be.

     (f) No Property Trustee or Delaware Trustee shall be liable for the acts or
omissions to act of any Successor Property Trustee or Successor Delaware
Trustee, as the case may be.

     6.7. Vacancies among Trustees. If a Trustee ceases to hold office for any
reason and the number of Trustees is not reduced pursuant to Section 6.1, or if
the number of Trustees is increased pursuant to Section 6.1, a vacancy shall
occur. A resolution certifying the existence of such vacancy by the
Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees shall be conclusive evidence of the existence of such
vacancy. The vacancy shall be filled with a Trustee appointed in accordance with
Section 6.6.

     6.8. Effect of Vacancies. The death, resignation, retirement, removal,
bankruptcy, dissolution, liquidation, incompetence or incapacity to perform the
duties of a Trustee shall not operate to annul, dissolve or terminate the Trust.
Whenever a vacancy in the number of Administrative Trustees shall occur, until
such vacancy is filled by the appointment of an Administrative Trustee in
accordance with Section 6.6, the Administrative Trustees in office, regardless
of their number, shall have all the powers granted to the Administrative
Trustees and shall discharge all the duties imposed upon the Administrative
Trustees by this Trust Agreement.

     6.9. Meetings. If there is more than one Administrative Trustee, meetings
of the Administrative Trustees shall be held from time to time upon the call of
any Administrative Trustee. Regular meetings of the Administrative Trustees may
be held at a time and place fixed by resolution of the Administrative Trustees.
Notice of any in-person meetings of the Administrative Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 48 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees shall be hand delivered
or otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 24 hours before a meeting. Notices shall
contain a brief statement of the time, place and anticipated purposes of the
meeting. The presence (whether in person or by telephone) of an Administrative
Trustee at a meeting shall constitute a waiver of notice of such meeting except
where an Administrative Trustee attends a meeting for the express purpose of
objecting to the transaction of any activity on the ground that the meeting has
not been lawfully called or convened. Unless provided otherwise in this Trust
Agreement, any action of the Administrative Trustees may be taken at a meeting
by vote of a majority of the Administrative Trustees present (whether in person
or by telephone) and eligible to vote with respect to such matter, provided



                                       30
<PAGE>

that a Quorum is present, or without a meeting by the unanimous written consent
of the Administrative Trustees. In the event there is only one Administrative
Trustee, any and all action of such Administrative Trustee shall be evidenced by
a written consent of such Administrative Trustee.

     6.10. Delegation of Power.

     (a) Any Administrative Trustee may, by power of attorney consistent with
applicable law, delegate to any natural person over the age of 21 his, her or
its power for the purpose of executing any documents contemplated in Section 3.6
or making any governmental filing; provided that such person is a United States
Person as defined in Section 7701(a)(30) of the Code.

     (b) The Administrative Trustees shall have power to delegate from time to
time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein;
provided, that such person is a United States Person as defined in Section
7701(a)(30) of the Code.

     6.11. Merger, Conversion, Consolidation or Succession to Business. Any
corporation into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with such Trustee may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of such Trustee shall be the successor of such Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

                                    ARTICLE 7

                               TERMS OF SECURITIES

     7.1. General Provisions Regarding Securities.

     (a) The Administrative Trustees shall on behalf of the Trust issue one
class of capital securities representing undivided beneficial interests in the
assets of the Trust and one class of common securities representing undivided
beneficial interests in the assets of the Trust.

          (i) Capital Securities. The Capital Securities of the Trust have an
     aggregate liquidation amount with respect to the assets of the Trust of up
     to ____________________ dollars ($______________) with respect to the
     closing of the sale of Capital Securities on one or more occasions. The
     Capital Securities are hereby designated for identification purposes only
     as "_____% Trust Preferred Securities" (the "Capital Securities"). The
     Capital Security Certificates evidencing the Capital Securities shall be
     substantially in the



                                       31
<PAGE>

     form of Exhibit A to this Trust Agreement, with such changes and additions
     thereto or deletions therefrom as may be required by ordinary usage, custom
     or practice or to conform to the rules of any stock exchange on which the
     Capital Securities are listed or quoted.

          (ii) Common Securities. The Common Securities of the Trust have an
     aggregate liquidation amount with respect to the assets of the Trust of up
     to _______________________ dollars ($______________) with respect to the
     closing of the sale of Common Securities on one or more occasions. The
     Common Securities are hereby designated for identification purposes only as
     "_______% Common Securities" (the "Common Securities" and, together with
     the Capital Securities, the "Securities"). The Common Security Certificates
     evidencing the Common Securities shall be substantially in the form of
     Exhibit B to this Trust Agreement, with such changes and additions thereto
     or deletions therefrom as may be required by ordinary usage, custom or
     practice.

     (b) Payment of Distributions on, and payment of the Redemption Price upon a
redemption of, the Capital Securities and the Common Securities, as applicable,
shall be made Pro Rata based on the liquidation amount of such Capital
Securities and Common Securities; provided, however, that if on any date on
which amounts payable on distribution or redemption, an Indenture Event of
Default shall have occurred and be continuing, no payment of any Distribution
on, or Redemption Price of, any of the Common Securities, and no other payment
on account of the redemption, liquidation or other acquisition of such Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions on all of the outstanding Capital Securities for all
Distribution periods terminating on or prior thereto, or, in the case of amounts
payable on redemption, the full amount of the Redemption Price for all of the
outstanding Capital Securities then called for redemption, shall have been made
or provided for, and all funds available to the Property Trustee shall first be
applied to the payment in full in cash of all Distributions on, or the
Redemption Price of, the Capital Securities then due and payable. The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Capital Securities and the Common Securities.

     (c) The Certificates shall be signed on behalf of the Trust by an
Administrative Trustee. Such signature shall be the manual or facsimile
signature of any present or any future Administrative Trustee. In case an
Administrative Trustee of the Trust who shall have signed any of the
Certificates shall cease to be such Administrative Trustee before the
Certificates so signed shall be delivered by the Trust, such Certificates
nevertheless may be delivered as though the person who signed such Certificates
had not ceased to be such Administrative Trustee; and any Certificate may be
signed on behalf of the Trust by such persons who, at the actual date of
execution of such Certificate, shall be the Administrative Trustees of the
Trust, although at the date of the execution and delivery of the Trust Agreement
any such person was not such an Administrative Trustee. Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by their
execution thereof, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements as the
Administrative Trustees may deem appropriate, or as may be required to comply
with any law or with any rule or regulation of any stock exchange on which
Securities may be listed, or to conform to usage.




                                       32
<PAGE>

               A Certificate representing Capital Securities shall not be valid
          until authenticated by the manual signature of an Authorized Officer
          of the Property Trustee. Such signature shall be conclusive evidence
          that such Certificate has been authenticated under this Trust
          Agreement.

               Upon a written order of the Trust signed by one Administrative
          Trustee, the Property Trustee shall authenticate the Certificates
          representing Capital Securities for original issue. The aggregate
          amount of Capital Securities outstanding at any time shall not exceed
          the liquidation amount set forth in Section 7.1(a)(i).

               The Property Trustee may appoint an authenticating agent
          acceptable to the Trust to authenticate Certificates. An
          authenticating agent may authenticate Certificates whenever the
          Property Trustee may do so. Each reference in this Trust Agreement to
          authentication by the Property Trustee includes authentication by such
          agent. An authenticating agent has the same rights as the Property
          Trustee to deal with the Sponsor or an Affiliate of the Sponsor.

     (d) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

     (e) Upon issuance of the Securities as provided in this Trust Agreement,
the Securities so issued shall be deemed to be validly issued, fully paid and
non-assessable undivided beneficial interests in the assets of the Trust.

     (f) Every Person, by virtue of having become a Holder or a Capital Security
Beneficial Owner in accordance with the terms of this Trust Agreement, shall be
deemed to have expressly assented and agreed to the terms of, and shall be bound
by, this Trust Agreement and the terms of the Securities.

     (g) The holders of the Securities shall have no preemptive or similar
rights.

     7.2. Distributions.

     (a) As owners of undivided beneficial ownership interests in the
Debentures, holders of Securities shall be entitled to receive cumulative cash
Distributions at the rate per annum of _______% of the stated liquidation amount
of $____ per Security. Pursuant to the Indenture, the amount of interest on the
Debentures payable for any period shorter than a full quarterly interest period,
and, as a result, Distributions on the Securities payable for any period shorter
than a full quarterly distribution period shall be computed on the basis of a
30-day month and for periods of less than a month, the actual number of days
elapsed per 30-day month. Subject to Section 7.1(b), Distributions shall be made
on the Capital Securities and the Common Securities on a Pro Rata basis.
Pursuant to the Indenture, interest on the Debentures shall, from the date of
original issue, accrue and be cumulative, and, as a result Distributions on the
Securities shall, from the date of original issue, accumulate and be cumulative.
Distributions



                                       33
<PAGE>

shall be payable quarterly in arrears on each _____________,
____________, _____________ and ________________ of each year, commencing
_____________, 20__, when, as and if available for payment, by the Property
Trustee, except as otherwise described below. Distributions are payable only to
the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent that the Trust has funds available for the
payment of such Distributions in the Property Account.

     (b) Pursuant to the Indenture, interest not paid on the scheduled payment
date will accrue and compound quarterly at the rate of _______% per annum, and,
as a result, interests on the Debentures not paid on the scheduled payment date
will accrue and compound quarterly at the rate of _______% per annum (and, as a
result) the Distributions on the Securities will accumulate and compound at the
rate of _______% per annum ("Compounded Distributions"). "Distributions" shall
mean ordinary cumulative distributions together with any Compounded
Distributions.

     (c) If and to the extent that the Debenture Issuer makes a payment of
interest, premium and/or principal on the Debentures held by the Property
Trustee (the amount of any such payment being a "Payment Amount"), the Property
Trustee shall and is directed, to the extent funds are available for that
purpose, make a Pro Rata distribution of the Payment Amount to Holders, subject
to Section 7.1(b).

     (d) Distributions on the Securities shall be payable to the Holders thereof
as they appear on the register of the Trust as of the close of business on the
relevant record dates. While the Capital Securities are represented by one or
more Global Securities, the relevant record dates shall be the close of business
the Business Day preceding such Distribution payment date; otherwise the
relevant record date shall be the fifteenth day (whether or not a Business Day)
preceding such Distribution payment date. At all times, the Distribution payment
dates shall correspond to the interest payment dates on the Debentures.
Distributions payable on any Securities that are not punctually paid on any
Distribution payment date, as a result of the Debenture Issuer having failed to
make a payment under the Debentures, shall cease to be payable to the Person in
whose name such Securities are registered on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with this Trust Agreement. If any date on which
Distributions are payable on the Securities is not a Business Day, then payment
of the Distribution payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), with the same force and effect as if made on such payment date.

     (e) In the event that there is any money or other property held by or for
the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata among the Holders of the Securities except as provided in
Section 7.1(b).

     7.3. Redemption of Securities.

     (a) Upon the repayment or redemption, in whole or in part, of the
Debentures



                                       34
<PAGE>

held by the Trust, whether at the stated maturity of the Debentures or upon
earlier redemption as provided in the Indenture, the proceeds from such
repayment or redemption shall be simultaneously applied Pro Rata (subject to
Section 7.1(b)) to redeem Securities having an aggregate liquidation amount
equal to the aggregate principal amount of the Debentures so repaid or redeemed
at the Redemption Price. Holders shall be given not less than 30 nor more than
60 days notice of such redemption in accordance with Section 7.4.

     (b) On the date fixed for any distribution of Debentures, upon dissolution
of the Trust, (i) the Securities will no longer be deemed to be outstanding and
(ii) certificates representing Securities will be deemed to represent the
Debentures having an aggregate principal amount equal to the stated liquidation
amount of, and bearing accrued and unpaid interest equal to accumulated and
unpaid distributions on, such Securities until such certificates are presented
to the Sponsor or its agent for transfer or reissuance.

     7.4. Redemption Procedures.

     (a) Notice of any redemption of, or notice of distribution of Debentures in
exchange for, the Securities (a "Redemption/Distribution Notice"), which notice
shall be irrevocable, will be given by the Trust by mail to each Holder of
Securities to be redeemed or exchanged not fewer than 30 nor more than 60 days
before the date fixed for redemption or exchange thereof which, in the case of a
redemption, will be the date fixed for redemption of the Debentures. For
purposes of the calculation of the date of redemption or exchange and the dates
on which notices are given pursuant to this Section 7.4(a), a
Redemption/Distribution Notice shall be deemed to be given on the day such
notice is first mailed by first-class mail, postage prepaid, to Holders of
Securities. Each Redemption/Distribution Notice shall be addressed to the
Holders of Securities at the address of each such Holder appearing in the
register of the Trust. No defect in the Redemption/Distribution Notice or in the
mailing of either thereof with respect to any Holder shall affect the validity
of the redemption or exchange proceedings with respect to any other Holder.

     (b) If fewer than all the outstanding Securities are to be so redeemed, the
Common Securities and the Capital Securities will be redeemed Pro Rata (subject
to Section 7.1(b)) and the Capital Securities to be redeemed will be redeemed as
described in Section 7.4(c) below. The particular Capital Securities to be
redeemed will be selected on a Pro Rata basis by the Property Trustee from the
outstanding Capital Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate. The Trust may not redeem the Securities in part
unless all accumulated and unpaid Distributions to the date of redemption have
been paid in full on all Securities then outstanding. For all purposes of this
Trust Agreement, unless the context otherwise requires, all provisions relating
to the redemption of Capital Securities shall relate, in the case of any Capital
Security redeemed or to be redeemed only in part, to the portion of the
aggregate liquidation amount of Capital Securities which has been or is to be
redeemed.

     (c) Subject to the Trust's fulfillment of the notice requirements set forth
in Section 7.4(a) above, if Securities are to be redeemed, then (i) with respect
to Capital Securities represented by one or more Global Securities, by 12:00
noon, New York City time, on the



                                       35
<PAGE>

redemption date, provided that the Debenture Issuer has paid the Property
Trustee a sufficient amount of cash in connection with the related redemption or
maturity of the Debentures, the Property Trustee will deposit irrevocably with
the Depositary or its nominee (or successor Clearing Agency or its nominee)
funds sufficient to pay the applicable Redemption Price with respect to the
Capital Securities and will give the Depositary irrevocable instructions and
authority to pay the Redemption Price to the Holders of the Capital Securities
and (ii) with respect to Securities not represented by one or more Global
Securities, provided that the Debenture Issuer has paid the Property Trustee a
sufficient amount of cash in connection with the related redemption or maturity
of the Debentures, the Property Trustee will give the Paying Agent irrevocable
instructions and authority to pay the relevant Redemption Price to the Holders
of such Securities upon surrender of their certificates evidencing the Capital
Securities. Payment of the Redemption Price on the Capital Securities will be
made to the recordholders thereof as they appear on the register of the Trust on
the relevant record date, which shall be one Business Day prior to the relevant
redemption date; provided, however, that with respect to the Capital Securities
not represented by one or more Global Securities, the relevant record date shall
be the date fifteen days prior to the relevant redemption date. If any date
fixed for redemption of Securities is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) with the same force and effect as if made on such date fixed for
redemption. If, however, the Business Day falls in the next calendar year, then
payment of the Redemption Price will be made on the immediately preceding
Business Day with the same force and effect as if made on such date fixed for
redemption. If payment of the Redemption Price in respect of any Securities is
not paid because the payment of the Redemption Price on the Debentures is not
made, interest will continue to accrue on the Debentures, and, as a result,
Distributions on such Securities will continue to accumulate at the then
applicable rate from the original redemption date to the actual date of payment,
in which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the Redemption Price. For these purposes,
the applicable Redemption Price shall not include Distributions which are being
paid to Holders who were Holders on a relevant record date. If a
Redemption/Distribution Notice shall have been given and funds deposited or paid
as required, then immediately prior to the close of business on the date of such
deposit or payment, Distributions will cease to accumulate on the Securities
called for redemption and all rights of Holders of such Securities so called for
redemption will cease, except the right of the Holders to receive the Redemption
Price, but without interest on such Redemption Price, and from and after the
date fixed for redemption, such Securities will cease to be outstanding.

          Neither the Administrative Trustees nor the Trust shall be required to
     register or cause to be registered the transfer of any Securities that have
     been called for redemption, except in the case of any Securities being
     redeemed in part, any portion thereof not to be redeemed.

     (d) Subject to the foregoing and applicable law (including, without
limitation, United States federal securities laws), the Debenture Issuer or its
subsidiaries may at any time and from time to time purchase outstanding Capital
Securities by tender, in the open market or by private agreement.

     7.5. Voting Rights of Capital Securities.

     (a) Except as provided under Section 6.6, Section 11.1 and this Article 7
and as otherwise required by the Business Trust Act, the Trust Indenture Act and
other applicable law, the Holders of the Capital Securities shall have no voting
rights.

     (b) Subject to the requirement of the Property Trustee obtaining a tax
opinion in certain circumstances set forth in Section 7.5(d) below, the Holders
of a Majority in Liquidation Amount of the Capital Securities voting separately
as a class have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or to direct the
exercise of any trust or power conferred upon the Property Trustee under the
Trust Agreement, including the right to direct the Property Trustee, as Holder
of the Debentures, to (i) exercise the remedies available to it under the
Indenture as a Holder of the Debentures; (ii) consent to any amendment or
modification of the Indenture or the Debentures where such consent shall be
required or (iii) waive any past default and its consequences that is waivable
under Section 5.13 of the Indenture; provided, however, that if an Indenture
Event of Default has occurred and is continuing, then the Holders of 25% of the
aggregate liquidation amount of the Capital Securities may direct the Property
Trustee to declare the principal of and interest on the Debentures due and
payable; provided, further, that where a consent or action under the Indenture
would require the consent or act of the Holders of more than a majority of the
aggregate principal amount of Debentures affected thereby, only the Holders of
the percentage of the aggregate stated liquidation amount of the Capital
Securities which is at least equal to the percentage required under the
Indenture may direct the Property Trustee to give such consent to take such
action.

     (c) If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of Capital Securities has made a written request, such
Holder of Capital Securities may, to the extent permitted by applicable law,
institute a legal proceeding directly against the Debenture Issuer to enforce
the Property Trustee's rights under the Indenture without first instituting any
legal proceeding against the Property Trustee or any other Person. In addition,
if a Trust Enforcement Event has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to make any interest,
principal or other required payments when due under the Indenture, then a Holder
of Capital Securities may directly institute a Direct Action against the
Debenture Issuer on or after the respective due date specified in the
Debentures.

     (d) The Property Trustee shall notify all Holders of the Capital Securities
of any notice of any Indenture Event of Default received from the Debenture
Issuer with respect to the Debentures. Such notice shall state that such
Indenture Event of Default also constitutes a Trust Enforcement Event. Except
with respect to directing the time, method, and place of conducting a proceeding
for a remedy, the Property Trustee shall be under no obligation to take any of
the actions described in clause 7.5(b)(i) and (ii) above unless the Property
Trustee has obtained an opinion of independent tax counsel to the effect that
the Trust will not be classified as an association or publicly traded
partnership taxable as a corporation for United States federal income tax
purposes as a result of such action.



                                       37
<PAGE>

     (e) In the event the consent of the Property Trustee, as the Holder of the
Debentures, is required under the Indenture with respect to any amendment or
modification of the Indenture, the Property Trustee shall request the direction
of the Holders of the Capital Securities with respect to such amendment or
modification and shall vote with respect to such amendment or modification as
directed by not less than a Majority in Liquidation Amount of the Capital
Securities voting together as a single class; provided, however, that where a
consent under the Indenture would require the consent of the Holders of more
than a majority of the aggregate principal amount of the Debentures, the
Property Trustee may only give such consent at the direction of the Holders of
at least the same proportion in aggregate stated liquidation amount of the
Securities. The Property Trustee shall not take any such action in accordance
with the directions of the Holders of the Securities unless the Property Trustee
has obtained an opinion of independent tax counsel to the effect that the Trust
will not be classified as an association or publicly traded partnership taxable
as a corporation for United States federal income tax purposes as a result of
such action.

     (f) A waiver of an Indenture Event of Default with respect to the
Debentures will constitute a waiver of the corresponding Trust Enforcement
Event.

     (g) Any required approval or direction of Holders of Capital Securities may
be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities or pursuant to
written consent. The Administrative Trustees will cause a notice of any meeting
at which Holders of Capital Securities are entitled to vote to be mailed to each
Holder of record of Capital Securities. Each such notice will include a
statement setting forth (i) the date of such meeting, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote and (iii) instructions for the delivery of proxies.

     (h) No vote or consent of the Holders of Capital Securities shall be
required for the Trust to redeem and cancel Capital Securities or distribute
Debentures in accordance with this Trust Agreement and the terms of the
Securities.

     (i) Notwithstanding that Holders of Capital Securities are entitled to vote
or consent under any of the circumstances described above, any of the Securities
that are owned at such time by the Debenture Issuer, any Administrative Trustee
or any entity directly or indirectly controlled by, or under direct or indirect
common control with, the Debenture Issuer or any Administrative Trustee, shall
not be entitled to vote or consent and shall, for purposes of such vote or
consent, be treated as if such Securities were not outstanding; provided,
however, that Persons otherwise eligible to vote to whom the Debenture Issuer or
any of its subsidiaries have pledged Capital Securities may vote or consent with
respect to such pledged Capital Securities under any of the circumstances
described herein.

     (j) Subject to Sections 6.6(a) and 7.5(k), Holders of the Capital
Securities shall have no rights to appoint or remove the Trustees, who may be
appointed, removed or replaced solely by the Common Securities Holder.

     (k) If an Indenture Event of Default has occurred and is continuing, the



                                       38
<PAGE>

Property Trustee and the Delaware Trustee may be removed at such time only by a
Majority in Liquidation Amount of the Capital Securities.

approved by a vote of the Holders of the Securities, except by a subsequent vote
of the Holders of the Securities.

     (a) Except as provided under Section 6.1(b), this Section 7.6 or Section
11.1 or as otherwise required by the Business Trust Act, the Trust Indenture Act
or other applicable law or provided by the Trust Agreement, the Holders of the
Common Securities will have no voting rights.

     (b) Subject to Sections 6.6(a) and 7.5(k), the Holders of the Common
Securities shall be entitled, in accordance with Article VI of this Trust
Agreement, to vote to appoint, remove or replace any Trustee or to increase or
decrease the number of Trustees.

     (c) Subject to Section 2.6 and only after all Trust Enforcement Events with
respect to the Capital Securities have been cured, waived, or otherwise
eliminated and subject to the requirement of the Property Trustee obtaining a
tax opinion in certain circumstances set forth in this paragraph (c), the
Holders of a Majority in Liquidation Amount of the Common Securities have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Property Trustee, or direct the exercise of any trust or
power conferred upon the Property Trustee under this Trust Agreement, including
the right to direct the Property Trustee, as Holder of the Debentures, to (i)
exercise the remedies available to it under the Indenture as a Holder of the
Debentures, (ii) consent to any amendment or modification of the Indenture or
the Debentures where such consent shall be required or (iii) waive any past
default and its consequences that is waivable under Section 5.13 of the
Indenture; provided, however, that where a consent or action under the Indenture
would require the consent or act of the Holders of more than a majority of the
aggregate principal amount of Debentures affected thereby, only the Holders of
the percentage of the aggregate stated liquidation amount of the Common
Securities which is at least equal to the percentage required under the
Indenture may direct the Property Trustee to have such consent or take such
action. Except with respect to directing the time, method, and place of
conducting a proceeding for a remedy, the Property Trustee shall be under no
obligation to take any of the actions described in clause 7.6(c)(i) and (ii)
above unless the Property Trustee has obtained an opinion of independent tax
counsel to the effect that, as a result of such action, for United States
federal income tax purposes the Trust will not be classified as other than a
grantor trust.

     (d) If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of Common Securities has made a written request, such
Holder of Common Securities may, to the extent permitted by applicable law,
directly institute a legal proceeding directly against the Debenture Issuer to
enforce the Property Trustee's rights under the Debentures without first
instituting any legal proceeding against the Property Trustee or any other
Person.

                                       39
<PAGE>

     (e) A waiver of an Indenture Event of Default with respect to the
Debentures will constitute a waiver of the corresponding Trust Enforcement
Event.

     (f) Any required approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities or pursuant to written
consent. The Administrative Trustees will cause a notice of any meeting at which
Holders of Common Securities are entitled to vote to be mailed to each Holder of
record of Common Securities. Each such notice will include a statement setting
forth (i) the date of such meeting, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote

     7.7. Paying Agent. In the event that any Capital Securities are not in
book-entry only form, the Trust shall maintain in the Borough of Manhattan, City
of New York, State of New York, an office or agency where the Capital Securities
may be presented for payment ("Paying Agent"). The Trust may appoint the paying
agent and may appoint one or more additional paying agents in such other
locations as it shall determine. The term "Paying Agent" includes any additional
paying agent. The Trust may change any Paying Agent without prior notice to the
Holders. The Trust shall notify the Property Trustee of the name and address of
any Paying Agent not a party to this Trust Agreement. If the Trust fails to
appoint or maintain another entity as Paying Agent, the Property Trustee shall
act as such. The Trust or any of its Affiliates may act as Paying Agent. The
Property Trustee shall initially act as Paying Agent for the Securities. In the
event the Property Trustee shall no longer be the Paying Agent, the
Administrative Trustees shall appoint a successor (which shall be a bank or
trust company acceptable to the Debenture Issuer) to act as Paying Agent. The
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Property Trustee and the Debenture Issuer.

     7.8. Listing. The Sponsor shall use its best efforts to cause the Capital
Securities to be included on the Nasdaq National Market.

     (a) Securities may only be transferred, in whole or in part, in accordance
with the terms and conditions set forth in this Trust Agreement and in the terms
of the Securities. To the fullest extent permitted by law, any transfer or
purported transfer of any Security not made in accordance with this Trust
Agreement shall be null and void.

     (b)  (i) Subject to this Article 7, Capital Securities shall be freely
transferable.

          (ii) The Holder of the Common Securities may not transfer the



                                       40
<PAGE>
Common Securities except (A) in compliance with a consolidation, merger, sale,
conveyance or lease of the Sponsor in compliance with Article VIII of the
Indenture or (B) to the Sponsor or an Affiliate thereof in compliance with
applicable law, including the Securities Act and applicable state securities and
blue sky laws. To the fullest extent permitted by law, any attempted transfer of
the Common Securities other than as set forth in the immediately preceding
sentence shall be null and void.

     (c) The Trust shall cause to be kept at the Corporate Trust Office of the
Property Trustee a register (the register maintained in such office being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Trust shall provide for the
registration of Capital Securities and of transfers of Capital Securities. The
Property Trustee is hereby appointed "Security Registrar" for the purpose of
registering Capital Securities and transfers of Capital Securities as herein
provided.

     (d) Upon surrender for registration of transfer of any Security at an
office or agency of the Trust designated for such purpose, the Trust shall
execute, and the Property Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like aggregate principal amount.

     (e) At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency. Whenever any Securities are so surrendered for exchange, the Trust shall
execute, and in the case of Capital Securities the Property Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

     (f) Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Trust or the Property Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Trust and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

     (g) No service charge shall be made for any registration of transfer or
exchange of Securities, but the Trust may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities.

     (h) If the Securities are to be redeemed in part, the Trust shall not be
required (i) to issue, register the transfer of or exchange any Securities
during a period beginning at the opening of business 15 days before the day of
the mailing of a notice of redemption of any such Securities selected for
redemption under Section 7.4 and ending at the close of business on the day of
such mailing, or (ii) to register the transfer or exchange of any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

     7.10. Mutilated, Destroyed, Lost or Stolen Certificates. If:



                                       41
<PAGE>

     (a) any mutilated Certificates should be surrendered to the Administrative
Trustees, or if the Administrative Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and

     (b) there shall be delivered to the Administrative Trustees such security
or indemnity as may be required by them to keep each of the Trustees, the
Sponsor and the Trust harmless,

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Administrative Trustee on behalf of the Trust shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like denomination.
In connection with the issuance of any new Certificate under this Section 7.10,
the Administrative Trustees may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

     7.11. Deemed Security Holders. The Trustees may treat the Person in whose
name any Certificate shall be registered on the register of the Trust as the
sole holder of such Certificate and of the Securities represented by such
Certificate for purposes of receiving Distributions and for all other purposes
whatsoever and, accordingly, shall not be bound to recognize any equitable or
other claim to or interest in such Certificate or in the Securities represented
by such Certificate on the part of any Person, whether or not the Trust shall
have actual or other notice thereof.

     7.12. Global Securities. On initial issuance, the Capital Securities may be
issued in the form of one or more Global Securities. If the Capital Securities
are to be issued in the form of one or more Global Securities, then an
Administrative Trustee on behalf of the Trust shall execute and the Property
Trustee shall authenticate and deliver one or more Global Securities that (i)
shall represent and shall be denominated in an amount equal to the aggregate
liquidation amount of all of the Capital Securities to be issued in the form of
Global Securities and not yet cancelled, (ii) shall be registered in the name of
the Depositary for such Global Security or the nominee of such Depositary, and
(iii) shall be delivered by the Property Trustee to such Depositary or pursuant
to such Depositary's instructions. Global Securities shall bear a legend
substantially to the following effect:

          This Capital Security is a Global Security within the meaning of the
     Trust Agreement hereinafter referred to and is registered in the name of
     The Depository Trust Company, a New York corporation (the "Depositary"), or
     a nominee of the Depositary. This Capital Security is exchangeable for
     Capital Securities registered in the name of a person other than the
     Depositary or its nominee only in the limited circumstances described in
     the Trust Agreement and no transfer of this Capital Security (other than a
     transfer of this Capital Security as a whole by the Depositary to a nominee
     of the Depositary or by a nominee of the Depositary to the Depositary or
     another nominee of the Depositary) may be registered except in



                                       42
<PAGE>

     limited circumstances. Unless this Capital Security Certificate is
     presented by an authorized representative of the Depositary to ASBC Capital
     ______ or its agent for registration of transfer, exchange or payment, and
     any Capital Security Certificate issued is registered in the name of Cede &
     Co. or such other name as requested by an authorized representative of the
     Depositary (and any payment hereon is made to Cede & Co. or to such other
     entity as is requested by an authorized representative of the Depositary),
     ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
     ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co.,
     has an interest herein.

     Capital Securities not represented by a Global Security issued in exchange
for all or a part of a Global Security pursuant to this Section 7.12 shall be
registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Property Trustee. Upon execution and authentication, the
Property Trustee shall deliver such Capital Securities not represented by a
Global Security to the Persons in whose names such definitive Capital Securities
are so registered.

     At such time as all interests in Global Securities have been redeemed,
repurchased or cancelled, such Global Securities shall be, upon receipt thereof,
cancelled by the Property Trustee in accordance with standing procedures of the
Depositary. At any time prior to such cancellation, if any interest in Global
Securities is exchanged for Capital Securities not represented by a Global
Security, redeemed, cancelled or transferred to a transferee who receives
Capital Securities not represented by a Global Security therefor or any Capital
Security not represented by a Global Security is exchanged or transferred for
part of Global Securities, the principal amount of such Global Securities shall,
in accordance with the standing procedures of the Depositary, be reduced or
increased, as the case may be, and an endorsement shall be made on such Global
Securities by the Property Trustee to reflect such reduction or increase.

     The Trust and the Property Trustee may for all purposes, including the
making of payments due on the Capital Securities, deal with the Depositary as
the authorized representative of the Holders for the purposes of exercising the
rights of Holders hereunder. The rights of the owner of any beneficial interest
in a Global Security shall be limited to those established by law and agreements
between such owners and depository participants provided, that no such agreement
shall give any rights to any Person against the Trust or the Property Trustee
without the written consent of the parties so affected. Multiple requests and
directions from and votes of the Depositary as holder of Capital Securities in
global form with respect to any particular matter shall not be deemed
inconsistent to the extent they do not represent an amount of Capital Securities
in excess of those held in the name of the Depositary or its nominee.

     If at any time the Depositary for any Capital Securities represented by one
or more Global Securities notifies the Trust that it is unwilling or unable to
continue as Depositary for such Capital Securities or if at any time the
Depositary for such Capital Securities shall no longer be eligible under this
Section 7.12, the Trust shall appoint a successor Depositary with respect to
such Capital Securities. If a successor Depositary for such Capital Securities
is not



                                       43
<PAGE>

appointed by the Trust within 90 days after the Trust receives such notice or
becomes aware of such ineligibility, the Trust's election that such Capital
Securities be represented by one or more Global Securities shall no longer be
effective and the Trust shall execute, and the Property Trustee will
authenticate and deliver, Capital Securities in definitive registered form, in
any authorized denominations, in an aggregate liquidation amount equal to the
principal amount of the Global Security or Capital Securities representing such
Capital Securities in exchange for such Global Security or Capital Securities.

     The Trust may at any time and in its sole discretion determine that the
Capital Securities issued in the form of one or more Global Securities shall no
longer be represented by a Global Security or Capital Securities. In such event
the Trust shall execute, and the Property Trustee, shall authenticate and
deliver, Capital Securities in definitive registered form, in any authorized
denominations, in an aggregate liquidation amount equal to the principal amount
of the Global Security or Capital Securities representing such Capital
Securities, in exchange for such Global Security or Capital Securities.

     Notwithstanding any other provisions of this Trust Agreement (other than
the provisions set forth in Section 7.9), Global Securities may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

     Interests of beneficial owners in a Global Security may be transferred or
exchanged for Capital Securities not represented by a Global Security and
Capital Securities not represented by a Global Security may be transferred or
exchange for Global Securities in accordance with rules of the Depositary and
the provisions of Section 7.9.

                                    ARTICLE 8

     8.1. Dissolution and Termination of Trust.

          (a) The Trust shall dissolve upon the earliest of:

               (i) the time when all of the Administrative Trustees and the
     Sponsor shall have consented to dissolution of the Trust provided such
     action is taken before the issuance of any Securities;

               (ii) at the Sponsor's election by at least 30 days written
     notice and direction to the Property Trustee to distribute the Debentures
     to the Holders of the Securities in exchange for all of the Securities,
     subject to the receipt of any necessary approvals by the Federal Reserve
     that may then be required under the applicable capital guidelines or
     policies of the Federal Reserve; provided that the Sponsor will be required
     to obtain an opinion of an independent counsel that the distribution of the
     Debentures will not be taxable to the Holders of the Capital Securities for
     United States federal income tax purposes;



                                       44
<PAGE>

          (iii) the time when all of the Securities shall have been called for
     redemption and the amounts then due shall have been paid to the Holders in
     accordance with the terms of the Securities;

          (iv) the bankruptcy of the Holder of the Common Securities or the
     Sponsor;

          (v) the filing of a certificate of dissolution or its equivalent with
     respect to the Sponsor or the revocation of the Sponsor's charter and the
     expiration of 90 days after the revocation without a reinstatement thereof;
     or

          (vi) the entry of a decree of judicial dissolution of the Sponsor or
     the Trust.

     (b) As soon as is practicable after the occurrence of an event referred to
in Section 8.1(a) and upon completion of the winding up and liquidation of the
Trust, the Trustees shall terminate the Trust by filing a certificate of
cancellation with the Secretary of State of the State of Delaware.

     (c) The provisions of Section 4.2 and Article 9 shall survive the
termination of the Trust.

8.2. Liquidation Distribution Upon Dissolution of the Trust.

     (a) In the event of any voluntary or involuntary liquidation, dissolution,
or winding-up of the Trust (each a "Liquidation"), the Holders of the Securities
on the date of the Liquidation will be entitled to receive, out of the assets of
the Trust available for distribution to Holders of Securities after satisfaction
of the Trust's liabilities to creditors, if any, distributions in cash or other
immediately available funds in an amount equal to the aggregate of the stated
liquidation amount of $_____ per Security plus accumulated and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless, in connection with such Liquidation, Debentures in an
aggregate stated principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the distribution rate of, and
accumulated and unpaid interest equal to accrued and unpaid Distributions on,
such Securities shall be distributed on a Pro Rata basis to the Holders of the
Securities in exchange for such Securities.

     (b) If, upon any such Liquidation, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Securities shall be paid on a Pro Rata basis. The Holders of the
Common Securities will be entitled to receive distributions upon any such
Liquidation Pro Rata with the Holders of the Capital Securities except that if
an Indenture Event of Default has occurred and is continuing, the Capital
Securities shall have a preference over the Common Securities with regard to
such distributions as provided



                                       45

     the capital contributions (or any return thereon) of the Holders of the
     Securities which shall be made solely from assets of the Trust; and

          (ii) shall not be required to pay to the Trust or to any Holder of

Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Trust Agreement or by law, except
that an Indemnified Person shall be liable for any such loss, damage or claim
incurred by reason of such Indemnified Person's negligence or willful misconduct
with respect to such acts or omissions.

     (b) An Indemnified Person shall be fully protected in relying in good faith
upon the records of the Trust and upon such information, opinions, reports or
statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with



                                       46
<PAGE>

reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be paid.

     9.3. Fiduciary Duty.

     (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Trust Agreement shall not be liable to the Trust or to another Covered Person
for its good faith reliance on the provisions of this Trust Agreement. The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person.

     (b) Unless otherwise expressly provided herein:

          (i) whenever a conflict of interest exists or arises between any
     Covered Person and any Indemnified Person; or

          (ii) whenever this Trust Agreement or any other agreement contemplated
     herein or therein provides that an Indemnified Person shall act in a manner
     that is, or provides terms that are, fair and reasonable to the Trust or
     any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Trust Agreement or any other
agreement contemplated herein or of any duty or obligation of the Indemnified
Person at law or in equity or otherwise.

     (c) Whenever in this Trust Agreement an Indemnified Person is permitted or
required to make a decision:

          (i) in its "discretion" or under a grant of similar authority, the
     Indemnified Person shall be entitled to consider such interests and factors
     as it desires, including its own interests, and shall have no duty or
     obligation to give any consideration to any interest of or factors
     affecting the Trust or any other Person; or

          (ii) in its "good faith" or under another express standard,

the Indemnified Person shall act under such express standard and shall not be
subject to any other or different standard imposed by this Trust Agreement or by
applicable law.

9.4. Indemnification.

     (a) The Debenture Issuer shall indemnify, to the full extent permitted by
law, any Indemnified Person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the Trust) by reason of the fact that he is or was an
Indemnified Person against expenses (including attorney fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Trust, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the Indemnified Person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Trust, and, with respect to any criminal action or proceeding,
had reasonable cause to believe that his conduct was unlawful.

     (b) The Debenture Issuer shall indemnify, to the full extent permitted by
law, any Indemnified Person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action or suit by or in the right
of the Trust to procure a judgment in its favor by reason of the fact that he is
or was an Indemnified Person against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Trust
and except that no such indemnification shall be made in respect of any claim,
issue or matter as to which such Indemnified Person shall have been adjudged to
be liable to the Trust unless and only to the extent that the Court of Chancery
of Delaware or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which such Court of Chancery or such
other court shall deem proper.

     (c) Any indemnification under paragraphs (a) and (b) of this Section 9.4
(unless ordered by a court) shall be made by the Debenture Issuer only as
authorized in the specific case upon a determination that indemnification of the
Indemnified Person is proper in the circumstances because he has met the
applicable standard of conduct set forth in paragraphs (a) and (b). Such
determination shall be made (i) by the Administrative Trustees by a majority
vote of a quorum consisting of such Administrative Trustees who were not parties
to such action, suit or proceeding, (ii) if such a quorum is not obtainable, or,
even if obtainable, if a quorum of disinterested Administrative Trustees so
directs, by independent legal counsel in a written opinion, or (iii) by the
Common Security Holder of the Trust.

     (d) Expenses (including attorneys' fees) incurred by a Debenture Issuer
Indemnified Person in defending a civil, criminal, administrative or
investigative action, suit or proceeding referred to in paragraphs (a) and (b)
of this Section 9.4 shall be paid by the Debenture Issuer in advance of the
final disposition of such action, suit or proceeding upon receipt of an



                                       48
<PAGE>

undertaking by or on behalf of such Debenture Issuer Indemnified Person to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Debenture Issuer as authorized in this Section 9.4.
Notwithstanding the foregoing, no advance shall be made by the Debenture Issuer
if a determination is reasonably and promptly made (i) by the Administrative
Trustees by a majority vote of a quorum of disinterested Administrative
Trustees, (ii) if such a quorum is not obtainable, or, even if obtainable, if a
quorum of disinterested Administrative Trustees so directs, by independent legal
counsel in a written opinion or (iii) by the Common Security Holder of the
Trust, that, based upon the facts known to the Administrative Trustees, counsel
or the Common Security Holder at the time such determination is made, such
Indemnified Person acted in bad faith or in a manner that such person did not
believe to be in or not opposed to the best interests of the Trust, or, with
respect to any criminal proceeding, that such Indemnified Person believed or had
reasonable cause to believe his conduct was unlawful. In no event shall any
advance be made in instances where the Administrative Trustees, independent
legal counsel or Common Security Holder reasonably determine that such person
deliberately breached his duty to the Trust or its Common or Capital Security
Holders.

     (e) The indemnification and advancement of expenses provided by, or granted
pursuant to, the other paragraphs of this Section 9.4 shall not be deemed
exclusive of any other rights to which those seeking indemnification and
advancement of expenses may be entitled under any agreement, vote of
stockholders or disinterested directors of the Debenture Issuer or Capital
Security Holders of the Trust or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office. All
rights to indemnification under this Section 9.4 shall be deemed to be provided
by a contract between the Debenture Issuer and each Indemnified Person who
serves in such capacity at any time while this Section 9.4 is in effect. Any
repeal or modification of this Section 9.4 shall not affect any rights or
obligations then existing.

     (f) The Debenture Issuer or the Trust may purchase and maintain insurance
on behalf of any person who is or was an Indemnified Person against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Debenture Issuer would
have the power to indemnify him against such liability under the provisions of
this Section 9.4.

     (g) For purposes of this Section 9.4, references to "the Trust" shall
include, in addition to the resulting or surviving entity, any constituent
entity (including any constituent of a constituent) absorbed in a consolidation
or merger, so that any person who is or was a director, trustee, officer or
employee of such constituent entity, or is or was serving at the request of such
constituent entity as a director, trustee, officer, employee or agent of another
entity, shall stand in the same position under the provisions of this Section
9.4 with respect to the resulting or surviving entity as he would have with
respect to such constituent entity if its separate existence had continued.

     (h) The indemnification and advancement of expenses provided by, or granted
pursuant to, this Section 9.4 shall, unless otherwise provided when authorized
or ratified, continue as to a person who has ceased to be a Debenture Issuer
Indemnified Person and shall



                                       49
<PAGE>

inure to the benefit of the heirs, executors and administrators of such a
person. The obligation to indemnify as set forth in this Section 9.4 shall
survive the resignation or removal of the Delaware Trustee or the Property
Trustee or the termination of this Trust Agreement.

     9.5. Outside Businesses. Subject to the provisions of Section 6.3, any
Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee may
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the
activities of the Trust, and the Trust and the Holders of Securities shall have
no rights by virtue of this Trust Agreement in and to such independent ventures
or the income or profits derived therefrom, and the pursuit of any such venture,
even if competitive with the activities of the Trust, shall not be deemed
wrongful or improper. Any Covered Person, the Sponsor, the Delaware Trustee or
the Property Trustee shall not be obligated to present any particular investment
or other opportunity to the Trust even if such opportunity is of a character
that, if presented to the Trust, could be taken by the Trust, and any Covered
Person, the Sponsor, the Delaware Trustee and the Property Trustee shall have
the right to take for its own account (individually or as a partner or
fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Covered Person, the Delaware Trustee and the Property Trustee
may engage or be interested in any financial or other transaction with the
Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee
or agent for, or act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.

                                   ACCOUNTING

     10.1. Fiscal Year. The fiscal year ("Fiscal Year") of the Trust shall be
the calendar year, or such other year as is required by the Code.

     10.2. Certain Accounting Matters.

          (a) At all times during the existence of the Trust, the Administrative
Trustees shall keep, or cause to be kept, full books of account, records and
supporting documents, which shall reflect in reasonable detail, each transaction
of the Trust. The books of account shall be maintained on the accrual method of
accounting, in accordance with generally accepted accounting principles,
consistently applied. The Trust shall use the accrual method of accounting for
United States federal income tax purposes. The books of account and the records
of the Trust shall be examined by and reported upon as of the end of each Fiscal
Year of the Trust by a firm of independent certified public accountants selected
by the Administrative Trustees.

          (b) The Administrative Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss.

          (c) The Administrative Trustees shall cause to be duly prepared and
delivered



                                       50
<PAGE>

to each of the Holders of Securities, an annual United States federal income tax
information statement, required by the Code, containing such information with
regard to the Securities held by each Holder as is required by the Code and the
Treasury Regulations. Notwithstanding any right under the Code to deliver any
such statement at a later date, the Administrative Trustees shall endeavor to
deliver all such statements within 30 days after the end of each Fiscal Year of
the Trust.

          (d) The Administrative Trustees shall cause to be duly prepared and
filed with the appropriate taxing authority, an annual United States federal
income tax return, on a Form 1041 or such other form required by United States
federal income tax law, and any other annual income tax returns required to be
filed by the Administrative Trustees on behalf of the Trust with any state or
local taxing authority.

     10.3. Banking. The Trust shall maintain one or more bank accounts in the
name and for the sole benefit of the Trust; provided, however, that all payments
of funds in respect of the Debentures held by the Property Trustee shall be made
directly to the Property Account and no other funds of the Trust shall be
deposited in the Property Account. The sole signatories for such accounts shall
be designated by the Administrative Trustees; provided, however, that the
Property Trustee shall designate the signatories for the Property Account.

     10.4. Withholding. The Trust and the Administrative Trustees shall comply
with all withholding requirements under United States federal, state and local
law. The Trust shall request, and the Holders shall provide to the Trust, such
forms or certificates as are necessary to establish an exemption from
withholding with respect to each Holder, and any representations and forms as
shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations. The Administrative
Trustees shall file required forms with applicable jurisdictions and, unless an
exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions. To the
extent that the Trust is required to withhold and pay over any amounts to any
authority with respect to distributions or allocations to any Holder, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to the Holder. In the event of any claimed over withholding, Holders shall be
limited to an action against the applicable jurisdiction. If the amount required
to be withheld was not withheld from actual Distributions made, the Trust may
reduce subsequent Distributions by the amount of such withholding.

          and that all conditions precedent to the execution and delivery of
          such amendment have been satisfied; and

          (iii) to the extent the result of such amendment would be to:

               (A) cause the Trust to be classified as other than a grantor
          trust for United States federal income tax purposes;

<PAGE>

          (ii) except as provided in Section 11.1(c)(i) hereof, any provision of
     this Trust Agreement may be amended by the Trustee and the Sponsor with (i)
     the consent of the Holders representing not less than a Majority in
     Liquidation Amount of the Securities outstanding and (ii) receipt by the
     Trustees of an opinion of counsel to the effect that such amendment or the
     exercise of any power granted to the Trustees in accordance with such
     amendment will not affect the Trust's status as a grantor trust for United
     States federal income tax purposes or the Trust's exemption from status of
     an Investment Company.

     (d) This Section 11.1 shall not be amended without the consent of all of

Securities, to:

          (v) to modify, eliminate and add to any provision of this Trust
     Agreement to ensure that the Trust will be classified as a grantor trust

     Securities are outstanding or to ensure that the Trust will not be required
     to register as an Investment Company under the Investment Company Act.

     11.2. Meetings of the Holders of Securities; Action by Written Consent.

     (a) Meetings of the Holders of any class of Securities may be called at any
time by the Administrative Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Trust Agreement, the
terms of the Securities or the rules of any stock exchange on which the Capital
Securities are listed or admitted for trading. The Administrative Trustees shall




                                       53
<PAGE>

call a meeting of the Holders of such class if directed to do so by the Holders
of at least 10% in Liquidation Amount of such class of Securities. Such
direction shall be given by delivering to the Administrative Trustees one or
more calls in a writing stating that the signing Holders of Securities wish to
call a meeting and indicating the general or specific purpose for which the
meeting is to be called. Any Holders of Securities calling a meeting shall
specify in writing the Certificates held by the Holders of Securities exercising
the right to call a meeting and only those Securities specified shall be counted
for purposes of determining whether the required percentage set forth in the
second sentence of this paragraph has been met.

     (b) Except to the extent otherwise provided in the terms of the Securities,
the following provisions shall apply to meetings of Holders of Securities:

          (i) notice of any such meeting shall be given to all the Holders of
     Securities having a right to vote thereat at least 7 days and not more than
     60 days before the date of such meeting. Whenever a vote, consent or
     approval of the Holders of Securities is permitted or required under this
     Trust Agreement or the rules of any stock exchange on which the Capital
     Securities are listed or admitted for trading, such vote, consent or
     approval may be given at a meeting of the Holders of Securities. Any action
     that may be taken at a meeting of the Holders of Securities may be taken
     without a meeting and without prior notice if a consent in writing setting
     forth the action so taken is signed by the Holders of Securities owning not
     less than the minimum amount of Securities in liquidation amount that would
     be necessary to authorize or take such action at a meeting at which all
     Holders of Securities having a right to vote thereon were present and
     voting. Prompt notice of the taking of action without a meeting shall be
     given to the Holders of Securities entitled to vote who have not consented
     in writing. The Administrative Trustees may specify that any written ballot
     submitted to the Security Holders for the purpose of taking any action
     without a meeting shall be returned to the Trust within the time specified
     by the Administrative Trustees;

          (ii) each Holder of a Security may authorize any Person to act for it
     by proxy on all matters in which a Holder of Securities is entitled to
     participate, including waiving notice of any meeting, or voting or
     participating at a meeting. No proxy shall be valid after the expiration of
     11 months from the date thereof unless otherwise provided in the proxy.
     Every proxy shall be revocable at the pleasure of the Holder of Securities
     executing such proxy. Except as otherwise provided herein, all matters
     relating to the giving, voting or validity of proxies shall be governed by
     the General Corporation Law of the State of Delaware relating to proxies,
     and judicial interpretations thereunder, as if the Trust were a Delaware
     corporation and the Holders of the Securities were stockholders of a
     Delaware corporation;

          (iii) each meeting of the Holders of the Securities shall be conducted
     by the Administrative Trustees or by such other Person that the
     Administrative Trustees may designate; and

          (iv) unless the Business Trust Act, this Trust Agreement, the terms of
     the Securities, the Trust Indenture Act or the listing rules of any stock
     exchange on which the Capital Securities are then listed for trading,
     otherwise provides, the Administrative Trustees, in their sole discretion,
     shall establish all other provisions relating to meetings of Holders of



                                       54
<PAGE>

     Securities, including notice of the time, place or purpose of any meeting
     at which any matter is to be voted on by any Holders of Securities, waiver
     of any such notice, action by consent without a meeting, the establishment
     of a record date, quorum requirements, voting in person or by proxy or any
     other matter with respect to the exercise of any such right to vote.
